Hi Julio,
Traffic policing controls the maximum rate of traffic sent or received on an
interface. Based on the results of the token bucket measurement, an action can
be configured to mark packets and separate packets into multiple classes or
levels of service.
For police rate Command

<http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cr/hqos_r
/qos_o1h.htm#wp1084265>
Use the police rate command to limit traffic that is destined for the control
plane on the basis of pps, bps, or a percentage of interface bandwidth
Examples
The following example shows how to configure policing on a class to limit
traffic to an average rate of 1500000 pps:
Router(config)# class-map telnet-class
Router(config-cmap)# match access-group 140
Router(config-cmap)# exit
Router(config)# policy-map control-plane-policy
Router(config-pmap)# class telnet-class
Router(config-pmap-c)# police rate 1500000 pps burst 500000 packets
Router(config-pmap-c)# exit

Subject: Police CIR and police rate.
Hi all,
Do anyone what is exactly the difference between those two configs:
policy-map HTTP
class HTTP
police cir 256000
and
policy-map HTTP
class HTTP
police rate 256000
Doing a IE lab I did the second config, but in the solutions i saw they did
the first, and I don4t understand why, so they are no using any burst or peak
rate.
Thanks in advance, Julio.
